Newer Base, McJava, ProtoData, and Validation

[alexander-yevsyukov]

This PR applies latest versions of code generation tools to core-java. The latest config was also applied, hence the number of modified files.

Other notable changes

• The MatchCriterion was updated to use binary name of a class instead of a canonical to handle the rare cases of referring methods in anonymous classes (which are sometimes used in tests).
• Logging in some tests was muted.
• AggregateTestSupport was converted to Kotlin and moved under testFixtures.

@alexander-yevsyukov LGTM. I haven't thoroughly reviewed buildSrc changes, though. Hopefully, it's the same set of files as in other repos.
